Abstract (en)
[origin: EP3018292A1] The invention concerns a turbine blade 10 comprising a surface 11, a recess within the surface 11, and a damping inlay 12 within the recess. The damping inlay comprises a chamber 14 with a damping material 16, for example particles. The damping inlay should substantially maintain the aerodynamic profile of the blade to enable normal operation. A further embodiment of the invention describes the method of manufacture of a turbine blade with a damping inlay. The method comprises the steps of manufacturing a turbine blade 10 having a surface and a recess in the surface, and providing one or more damping inlays 12 within the recess such that the damping inlay substantially maintains the aerodynamic profile of the blade, the damping inlay comprising a chamber 14 and a damping material 16 disposed within the chamber.
